Uns wurde am 28.03.2014 eine CNC-Maschine überlassen. Nachdem wir sie unter Verwendung des mitgelieferten Industrierechners ansteuern konnten, stellten wir fest, dass diese Methode nicht viel Zukunft haben würde. Kein USB, beschränkte Geschwindigkeit, laut, Win98 will man nicht im Netzwerk haben, etc.

Da die Fräse alle ihre Anschlüsse über D-Sub-Buchsen herausführt, wollen wir einen anderen Controller verwenden, der die Motoren direkt ansteuert. Am 24.05.2014 haben wir mit einem [http://smoothieware.org/smoothieboard Smoothieboard] erfolgreich die ersten Schritte in diese Richtung gemacht.

erste Inbetriebnahme, noch auf dem Frickelraumtisch
Beschreibung: CNC-Fräse
Ort: Werkstatt
Status: work in progress (Was heißt das?)
Kontakt: Daniel Bohrer, Kasalehlia, larsan, comawill, adnc
Usage Policy: Benutzung erst nach Einweisung. Kaputtmachen und Reparieren nur von Spezialexperten.
Hinweis:
Diese Seite befindet im Aufbau, es können Platzhalter vorkommen und wichtige Informationen fehlen. Inhaltliche Bearbeitungen und Ergänzungen, sowie Formatierungen sind ausdrücklich erwünscht.

Uns wurde am 28.03.2014 eine CNC-Maschine überlassen. Nachdem wir sie unter Verwendung des mitgelieferten Industrierechners ansteuern konnten, stellten wir fest, dass diese Methode nicht viel Zukunft haben würde. Kein USB, beschränkte Geschwindigkeit, laut, Win98 will man nicht im Netzwerk haben, etc.

Da die Fräse alle ihre Anschlüsse über D-Sub-Buchsen herausführt, wollen wir einen anderen Controller verwenden, der die Motoren direkt ansteuert. Am 24.05.2014 haben wir mit einem Smoothieboard erfolgreich die ersten Schritte in diese Richtung gemacht.

Stand 27.06.2014: Wir haben uns ein eigenes Smoothieboard 5X zugelegt, das wird derzeit in Betrieb genommen.

Überblick

Fräse

Durch den Aufbau als Portalfräse ist es möglich, dass Werkstücke in y-Richtung über den Frästisch hinausragen können

Es handelt sich um (Stand 2014) eine etwa 15 Jahre alte Isel Automation Flachbett-Tischfräse CNC Multi K. Kaum gebraucht und vermutlich seit ~9 Jahren nicht mehr in Betrieb gewesen, bevor sie 2014 zu uns kam.

  • maximaler Arbeitsbereich: (x,y,z) = (330 mm, 500 mm, 90 mm), abzüglich Befestigung und eingesetztem Fräser eher so z=70 mm
  • Kugelgewindetriebe
  • Zwei Endschalter pro Achse
  • Derzeit zwei Frässpindeln verfügbar
  • NEMA23 Schrittmotoren der Firma Nanotec 4T5618M3300

Motoranschlüsse an der Fräse

Die Fräse führt an der Hinterseite 3 D-Sub DE-9 Buchsen heraus, die je für die Ansteuerung der X-, Y- und Z-Achse zwei Polepaaranschlüsse bereitstellt. Pinbelegung D-Sub DE-9 Buchsen

2. Pol /A
3. Pol B

In der Fräse selbst steckt keine Logik, die Achsen werden über drei D-Sub-Buchsen aus der Fräse herausgeführt.

Die etwas komische Belegung der CNC-Fräse

Endschalter

  • X-Achse: Endschalter für min. und max. sind vorhanden
  • Y-Achse: Endschalter für min. und max. sind vorhanden
  • Z-Achse: Endschalter für min. und max. sind vorhanden

Die Entschalter mit NC (Normally Connected) an den jeweiligen D-Sub DE-9 Buchsen mit den Pins 5 (Common), 7 und 9 angeschlossen. Auf dem 25-Pol Kabel ist allerdings Pin 9 Common. Das sollte sich durch umlöten der Stecker an der CNC-Fräse aber ändern lassen.

Werkzeuge

Proxxon

  • 230V, 100W
  • 20k 1/min direkt am Gerät stufenlos verstellbar
  • Wird direkt an den Rechner angeschlossen
  • Mit Aufnahmen für verschiedene Einsatz-Durchmesser bis 3.2 mm
  • Das vordere Lager wurde durch Proxxon kostenlos getauscht und ist somit wieder i.O.

HF-Spindel

  • Wird von einem externen Netzteil mit Strom versorgt, das wiederum über "Fußpedal"-Anschluss mit Rechner ("HF-Spindel") verbunden wird. (Kann kurzgeschlossen werden, die Spindel ohne den Rechner zu betreiben.
  • 50k 1/min

Erste Experimente

Erste CNC Experimente
  • Anschluss an ein SmoothieBoard
  • Config angepasst (Siehe Upload von larsan)
  • Mit Eagle und pcb-gcode gcode erzeugt, auf SmoothieBoard übertragen und ausgeführt
  • Noch einige Probleme mit der Einstellung der Höhe(Z-Achse), da der Kleber unter der Platine etwas uneben war

Workflow

  1. Model (CAD)
  2. Fräsanweisungen (CAM)
    Erzeugen der Fräsanweisungen/Maschinenanweisungen mit einer CAM.
    Wir suchen noch nach einer brauchbaren Open-Source Lösung.
  3. Simulation
  4. Übertragen auf CNC-Controller Smoothieboard
    • Per Dateiupload (Datenträger von Smoothieboard, SD-Karte) SmoothieControl
      • notfalls kann man das SmoothieBoard auch über USB mit dem Befehl net in Pronterface oder über die serielle Konsole nach seiner IP-Adresse fragen
  5. Koordinatensystem der Fräse setzen
    • Fräse per Smoothie WebApp auf den gewünschten Nullpunkt fahren
    • per Webapp den G-Code "G92 X0 Y0 Z0" senden (Setzt aktuelle Position als X:0, Y:0, Z:0 im globalen Koordinatensystem.)
  6. Fräsen

Parameter für verschiedene Werkstoffe

Parameter finden sich sind auf der Unterseite CNC-Fräse/Parameter

Steuern des Smoothieboards

  • Per seriell Verbindung über Konsole "screen /dev/ttyACM0 115200", oder Pronterface GUI
  • Per Netzwerkverbindung über Konsole mit Telnet, oder Http Web UI
  • Mittlerweile existiert sogar eine Android App SmoothieControl
  • bCNC ermöglicht das Senden von GCODE-Anweisungen und Visualisierung der Fräsbahnen in einer GUI.
